Water vapor transmission rate tester WVTR-W6

for filmfor productionmedical

WVTR-W6 Water Vapor Transmission Rate Tester, based on the Gravimetric method, provide a wide range and high efficiency water vapor transmission rate testing experience for low, medium and high water vapor barrier materials. It is suitable for the measurement of water vapor transmission rate of various materials such as plastic film, composite film, medical treatment, construction, etc. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production. Product Features Advanced Technology -Dual test mode: Desiccant method and Water method -Equipped with high-precision weighing system, which can improve the system sensitivity and stability -A new generation of circular structure test chamber design, making the temperature and humidity distribution more uniform -Wide-range, high-precision, automatic temperature and humidity control, meet various test needs -Standard air velocity prevents water vapor from condensing on top of test dishes, ensuring a constant humidity difference between the inside and outside of the test dishes -Self-developed periodically weighing method and auto zero before each weighing guarantee the accuracy and uniformity of the testing data -Convenient fast-access calibration ports for temperature and humidity calibration. -Reference film or standard weight for fast and accurate calibration -Precision mechanical design not only ensures the system's ultra-high precision, but also greatly improves the test efficiency
